Inserting Unicode in Emacs

This was a very nice surprise; I've never seen anything like it in any other editor.

To insert a Unicode character, use C-x 8 RET. An interactive menu will appear where you can search for the character you want by name.

For example, the command:

C-x 8 RET BANKNOTE WITH EURO SIGN RET

Emacs Unicode Input

...inserts the 💶 character into the buffer:

Mind blowing... 🤯🤯🤯
